IMPROVEMENT IN BILLIARDTABLE CUSHIONS.

Specification forming part of Letters Patent No. 143,961, dated October 28, 1873; application filed June 11,1872.

To all whom it may concer/u.: j

Be it known that we, SOLOMON BaUNsWoK and HENRY BoRLrNGHAUs, Sr., of St. Louis, county of St. Louis and State of Missouri, have made certain new and useful Improvements in Billiard-Table Cushions; and we do hereby declare that the following is a full and true description thereof, reference being had` to the A accompanying drawings and to the letters of reference marked thereon.

The improvements here shown have for objects the removal of certain defects in the use of rubber as well as steel-plate cushions.

The invention relates to a new and peculiar formation and arrangement of metallic springplates, in combination with india-rubber facings and bearings, forming an improved steelplate cushion, possessing` advantages of form, structure, and spring power, all of which will now more fully appear.

To enable those herein skilled to make and use our said improvements, we will now more fully describe the same, referring` to the gure as representing a transverse section.

A is the bed of the table 5 B, the ball. O is the ordinary railing. The metallic cushion consists of the body steel platesc c1, which are properly tempered to required elasticity. The plate c is slightly shaped, curved, or inclined inward at its top edge, so as to produce the projecting edge c2 of the cushion, the obj ect of the projecting edge c2 being to concentrate the spring-action of the cushion to the point or surface, against which the ball impinges, to give to the ball the required spring power, and to add shape and conformity to the cushion. The plate c1 is shorter in width, and is arranged back or to the inner side ofthe plate c. Said plate c1, by its contiguous action, increases the spring power of the cushion, according to the force of the ball, prevents the same bedding in,77 and otherwise adds effectiveness and correct springaction to the cushion. To lessen the sound from concussion of the ball green cloth c3 is wound about the plate c1, and the several parts, the plates c c1 and cloth c?, are solidly secured to the lower beveled edge ofthe railing C, as clearly shown in the figure. To prevent springing action of the steel cushion c against the wood railing O, the same is properly mortised to receive a rubber bearing or strip, D, which is arranged lengthwise and properly secured to the railing. The rubber bearing D also prevents undue jarring, and graduates the concussion, so that the ball at all times, and with what force the same may be impelled, is acted upon by an eective spring or elastic action. The upper steel platel d, which is properly set in and secured to the wooden railing, adds to the formation of the shape of the cushion, as well as giving to same strength, rigidness, and

solidity. E is a rubber or elastic facing cove ering the steel plates. Said facing deadens the sound of concussion, as well as protects and completes the triangular shape of the steel cushion. The body or inside hollow of the cushion can be stuifed with suitable material to deaden all noise.

` As ordinarily the entire cushion is covered with a green cloth, e.

Our improved cushion, it will be noticed, presents to the ball a genuine spring power, which is more equally distributed on impact of the ball, producing the most accurate angles; and, otherwise, our said cushion possesses superiority over ordinary rubber or metallic cushions in cheapness, durability, and elastic action.

Having thus fully described our said invention, what we claim, and desire to secure by Letters Patent, is s The billiard-cushion described, having the steel-plate springs c cl, rubber coveringI E, and buffer D, constructed and arranged as :and for the purpose specified.

In testimony of said invention we have hereunto set our hands.
